黑熊瘘管引流道产量统计及分析

胆皮口缝合术坏死性瘘管引流道的基数引流系数为0.82,每只每日胆粉均值为5.91.据某场9年的胆粉总产量年均值为51 328 g,每只每日均值为7.36 g,胆粉率为14.41%,引流系数为0.95.此种引流道靠重复手术,将胆粉日均值提高到1.45 g/只,其增加的幅度为基数的24.53%,引流系数提高到12%.经取胆前3年与后3年,胆粉产量低产月与高产月的统计及观察发现一些规律性问题.

Black bear road fistula drainage output statistics and analysis

Base drainage coefficient of necrotic fistula drainage channel by suturing bilis and skin opening is 0.82,bile powder daily average per bear is 5.91 g.On a bear farm,annual average output of bile powder in 9 year was 51 328 g,daily average each bear was 7.36 g,bile powder rate is 14.41%,the drainage coefficient is 0.95.Such drainage channel by repeated surgery,bile powder daily average increased to 1.45 g per bear,and increasing range of the base drainage coefficient is 24.53%,the drainage coefficient increased to 12%.Comparison of bile powder output of the previous three years and the first three years,by statistical analysis and observation,we detected regularity problem and draw some conclusions.
